Granted: 1989-04-12
Abstract: Une matrice de rangées (102-1) et de colonnes (101-2) d'électrodes en bande est utilisée pour commuter des cellules bistables d'affichage à cristaux liquides de l'état vertical à l'état horizontal par chauffage résistif en appliquant un courant électrique d'une valeur et d'une durée suffisantes aux électrodes sélectionnées (102-1, 102-2). Sous l'effet du chauffage résistif, il se produit dans les cristaux liquides (130) une transition de phase de la mésophase nématique à une phase isotrope. L'extinction du courant permet aux cristaux liquides de refroidir de préférence dans l'état horizontal de la mésophase nématique. La commutation de l'état horizontal à l'état vertical est obtenue grâce à des techniques conventionnelles d'effet de champ électrique. Il est ainsi possible de réaliser des dispositifs ayant un fonctionnement plus rapide.
